AI Technical Summary
Technical Problem
Existing SSDs do not provide clear notifications when they enter thermal shutdown, leaving users and hosts unaware of when normal functioning can be expected, especially when used as primary drives.
Method used
Implementing asynchronous event notifications (AENs) that include cool-off wait times, allowing hosts to issue banners with restart instructions, enabling manual or automatic SSD restarts after a predetermined cool-off period.
Benefits of technology
Enables informed decision-making by users and hosts regarding SSD restarts, preventing ungraceful shutdowns and ensuring timely recovery of SSD performance.

Abstract
The present disclosure generally relates to improved wait time notifications from SSDs to host systems. Rather than assuming on when to restart an SSD after an asynchronous event notification (AEN) is sent, issuing a cool-off wait time. When an SSD is overheating, an AEN is sent from the SSD. An AEN may either be a warning event or a critical event. Once the AEN is received, a host may issue a banner with a cool-off wait time. The cool-off wait time is a predetermined time that will begin if the SSD is not detected by host systems. A non-detectable SSD means that the SSD is in a thermal shut down mode, which is initiated by a PMIC. In the thermal shut down mode, the cool-off wait timer will begin at host side. After the time has elapsed the SSD can then be restarted either manually by user or automatically by host.
